Supernova Remnants Cas-A and Crab
Images of the two young supernova remnants Cas-A and Crab, observed with the spatially high resolution imaging X-ray camera (HRI) onboard ROSAT (lower panel) and with a charged coupled device (CCD) silicon chip camera onboard the X-ray observatory Chandra (NASA/CXC/SAO) launched into orbit in Summer 1999 (upper panel). The angular resolution in the ROSAT image is about 5 arcseconds. The Chandra instrument with an angular resolution of only one arcsecond allows to detect even finer structures and weaker point sources in the X-ray images. With Chandra an X-ray sources in the center of Cas A was identified for the first time which is either a neutron star born in a supernova explosion or a stellar black hole.
